废旧泡沫塑料的回收利用

Waste Foamed Polystyrene Recycling and Reclamation

将废旧泡沫磺化制备聚苯乙烯磺酸及其钠盐,目标产品是具有良好絮凝性能的助凝剂。以产品和聚合硫酸铁对陶瓷废水进行絮凝净化试验,取得了良好效果,并研究了最佳实验条件。结果表明,使用两者可以提高絮凝效果,用聚苯乙烯磺酸钠作为助凝剂的处理成本低和方法简单,值得推广应用。这对废旧泡沫的回收利用有明显的效果,减少对环境的危害。

Polystyrene sulfonic acid and its sodium salt were prepared with waste foamed polystyrene. The goal product was the assistants of coagulant. It was efficient to treat the ceramics waste water by polystyrenc sulfonic acid and polyferrie sulfate, the optimum experimental conditions were researched. The results shown that the use of them can effectively increase the speed of precipitating, polystyrene sulfonic acid and its sodiumsalt worth applying for its cost effectiveness and the methods were simple as the assistants of coagulant. The recycling of waste foam had a significant effect, reducing harm to the environment.
